לֹֽא־תִקֹּ֤ם וְלֹֽא־תִטֹּר֙ אֶת־בְּנֵ֣י עַמֶּ֔ךָ וְאָֽהַבְתָּ֥ לְרֵעֲךָ֖ כָּמ֑וֹךָ אֲנִ֖י יְהֹוָֽה׃
You shall not take vengeance or bear a grudge against members of your people. Love your fellow* as yourself: I am GOD.
*fellow See note at v. 13, and cf. v. 34.
(The above rendering comes from the RJPS translation, an adaptation of the NJPS translation.)
On the noun רֵעַ and its rendering, seem my comment at v. 13.
